I have read most of the books mentioned. One of my great winter pleasures is a good book which translates to hunting and usually means Africa. It's hard to get a new one from Safari Press as I have most. One that I enjoyed greatly that I haven't seen mentioned is Kambaku by Harry Manners. If you like the old ivory hunters you'll like this one. It has recently been re released by Safari Press.
Right now I'm reading Some Lions I Have Met by Gordon Cundill.
Amwell Press (long out of business sadly) put out some great African books especially their anthologies on the big 5.
